Background: Dengue fever is a major public health problem with an increase incidence in recent years. Dengue fever is an acute – mosquito transmitted viral infectioncausedby1to4serotypes (DEN-1, DEN-2, DEN-3 and DEN-4) of the genus flavivirus. It is the most common arboviral disease in the world. Dengue fever has been known for more than a century in the tropical area of south East Asia and the Western Pacific regions. Dengue fever is the most rapidly spreading mosquito borne viral disease of mankind, with a 30 fold increase in global incidence over the last five decades. This study is to identify ultrasonographic findings in Dengue fever & to study the clinical significance of Gall Bladder Wall thickness in persisting the severity of Dengue fever. This is a Observational prospective study of 100 patients admitted with seropositive for dengue fever at tertiary care hospital, who fulfilled the inclusion and exclusion criteria during the period of July 2018 to June 2020. Results: Majority of cases of dengue fever was occurred in patients age range from 18 to 27 years with mean age 31.2. In present study Dengue Fever was diagnoses in 70% of all cases while Dengue Hemorrhagic Fever in 22% and Dengue Shock Syndrome in 08% of them. Fever is most common clinical feature (96%) followed by Myalgia (61%). In this study we found that in patient with dengue, in USG findings over all frequency of GBWT was 65% followed by ascites 30%, Pleural effusion 23%, Hepatomegaly 19% and Splenomegaly 16%. In the present study GBWT did not show any relation to biochemical blood test or hematological parameters. Hemoconcentration once thought to be significantly linked to increased Dengue se- verity, appears unlinked to dengue severity as measured by plasma leakage and GBWT. Conclusion: Gall Bladder Wall thickness is one of the most common finding in Dengue Fever. GB wall thickness more than 6mm is associated with severe Dengue fever with significant statistical correlation.
